appeared on my dash last night right before pulling in my driveway. I checked the oil and had none on my stick. 2500 miles on the truck at this point. It's at the shop, so I'll see what they come up with tomorrow. Anyone else experienced this? At this point, it's either burning it, there's a leak, or they didn't give it a good inspection before I picked it up.

That’s odd. It could be couple things that you mentioned. Maybe PDI didt fill oil level correctly. Wouldn’t hurt to change the oil now.

If you lost like 3 quarts of oil, you'd see the leak...
If you burned the same amount, you'd see blue smoke out the exhaust.
If a head gasket popped and oil was getting into the cooling system, you'd see that extra 3 quarts of contaminated crud leaking out.
If coolant was also getting into the oil, you'd see a milkshake on the dipstick even if the engine was low on oil.

If you added a couple-3 quarts and topped it off, then you could gauge whether it was an actual issue or just under-filled at the factory.
The dealer won't be able to do a thing, barring observing the first 4 issues, none of which are likely, or they'd be obvious.
2500mi, I'd change the oil anyway. And then get a baseline for the issue, if there is one.

The truck was driven to the dealership from another dealership 175 miles away. My dealership admitted to not inspecting the vehicle because they assumed the dealership it came from did, so they didn't check it at all. I had them change the oil and we'll go from here. I hope no damage was done, but I'll find out the hard way I'm sure. Thanks for the responses

I'd say rest easy. 1,000,000s of larger motors than the little LS mouse motors in our trucks have run off of a total oil capacity of 5 quarts for a long time.
And the oil pump sump in the LS I've seen apart was pretty close to the bottom of the pan. Moreso, I think many of these larger oil capacities on newer engines are more than partly to allow longer OCI's. If it's not ticking or knocking, nothing got oil starved.
